Glycosyltransferases, Mutants and Their Applications

摘要

The present invention relates to glycosyltransferases, mutants and their applications. Specifically, in the presence of glycosyltransferase, the glycosyl group of the glycosyl group donor is transferred to the hydroxyl group of the C-3 region of the tetracyclic triterpenoid compound; Forming a glycosylated tetracyclictriterpenoid-based compound; Wherein the glycosyltransferase is a glycosyltransferase represented by SEQ ID NO .: 4 or a derivative polypeptide thereof; Or a glycosyltransferase or a derivative polypeptide thereof represented by SEQ ID NO .: 21.
